1. NRV reducer is a novel transmission device that applies the principle of planetary transmission and adopts the meshing of cycloidal pin teeth. In the gear box, bearing box, thread seal, mechanical seal and other parts of the cycloid pinwheel reducer, due to the long-term high-torque mechanical movement, the meshing gap of the gear box becomes larger, causing greater noise and equipment vibration. During the operation of the helical gear hardened gear reducer, the temperature in the box rises, the gas expands, and the pressure increases. In order to freely discharge the thermal expansion air in the box, and to maintain the pressure balance inside and outside the box, so as not to cause the lubricating oil to leak along the nominal or axial extension seal of the box, a vent cap is usually installed on the top of the box;

2.NRV reducer is widely used in our country and is used in the turning structure of tower-introduction crane machinery. It is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical industry, textile, printing and dyeing, pharmacy, etc. . The bearing cover is to fix the axial direction of the shaft system components and bear the axial load, and the two ends of the bearing seat hole are closed by the bearing cover;

3. In order to ensure the manufacturing accuracy of the bearing seat hole every time the packing cover is removed, before the bearing hole is realized, the positioning pin should be installed on the connecting flange of the box cover and the box seat;

4. NRV reducer is a fresh transmission device that uses the principle of planetary transmission and adopts the meshing of cycloidal needle teeth. The entire transmission device of the cycloid reducer can be divided into three parts: input part, deceleration part, and output part. The oil level instigator checks the height of the oil level in the oil sump of the helical gear hard-tooth surface reducer, and always ensures that there is an appropriate amount of oil in the oil sump;

5. NRV pin gear reducer is a novel transmission device that applies the principle of planetary transmission and adopts the meshing of cycloidal pin teeth. The gear box, bearing box, thread seal, mechanical seal and other parts of the NRV reducer, due to long-term high-torque mechanical movement, the gear box meshing gap becomes larger, resulting in greater noise and equipment vibration. When replacing the oil with the unloading screw plug, drain the dirty oil and the detergent. Open the drain hole at the bottom of the tank seat and the lowest direction of the oil pool. The drain hole is usually blocked with a screw plug. A leak-proof gasket is installed between.

The important feature of the NRV reducer is the reverse self-locking function and the larger reduction ratio. Planetary cycloid reducer is a relatively new type of transmission mechanism. Its unique and stable structure can replace ordinary cylindrical gear reducers and worm gear reducers in many cases, because the planetary cycloid reducer has high speed ratio, high efficiency and compact structure. , Small size, stable operation, low noise, reliable use, long life, reasonable design, convenient maintenance, easy to disassemble and install. The input shaft and the output shaft are not on the same axis or on the same plane. But the individual is large in size, the transmission efficiency is not high, and the accuracy is not high. The harmonic drive of the harmonic reducer adopts the elastic deformation controlled by the flexible element to transmit the activity and energy. Its small size and high precision, but its fault is that the flexible wheel has limited service life, poor impact resistance, and poor rigidity compared with the metal complete machine.

The input speed should not be too high. The utility model has compact structure, small return gap, high precision, long service life and large rated output torque. However, it is more expensive. The cycloid reducer has the characteristics of small size and large transmission torque. NRV reducer is designed and manufactured on the basis of modular combination system. There are many motor combinations, installation situations and structural plans. The transmission ratio is fine, which can adapt to different working conditions and realize electromechanical integration. NRV reducers have the advantages of high transmission efficiency, low energy consumption and superior performance. NRV pin gear reducer is a transmission form that adopts the principle of cycloidal pin tooth meshing planetary transmission. It is a fantasy transmission device. It has many advantages, is universally useful, and may run forward and backward.
